OBJECTIVETo evaluate the clinical outcomes and complications of Triple-Endobutton plates in treating Tossy type III acromioclavicular joint dislocation.
METHODSFrom January 2011 to January 2013,45 patients with Tossy type III acromioclavicular joint dislocation were treated with Triple-Endobutton plates. There were 35 males and 10 females with an average age of 30.5 (ranged from 19 to 60) years old. At the final follow-up, VAS, DASH, Constant-Murley criterion were used to evaluate shoulder function.
RESULTSAll patients were followed up from 15 to 36 months. No neurovascular injury, wound infection and stress fractures were found,but 3 patients had a re-dislocation. At the final follow-up,the mean VAS score was decreased from (5.7±1.6) preoperatively to postoperative (0.2±0.1); DASH score was significantly decreased from (19.6±4.3) preoperatively to (0.3±0.1) postoperatively; Constant-Murley score was improved from (34.4±4.3) before operation to (94.8± 3.5) after operation.
CONCLUSIONClinical outcomes of treating Tossy type III acromioclavicular joint dislocation with Triple-Endobutton plates is satisfactory. However, re-dislocation is still the most common complication. Careful perioperative management is an important factor in preventing re-dislocation.

The traditional Chinese medicine (TCM) theory of "treating heart and brain diseases with same methods (Nao Xin Tong Zhi: NXTZ)" has great significance to the treatment of cardiovascular and cerebrovascular diseases. It has been proven effective by a great deal of clinical researches. However, the underlying mechanism for this theory is still unclear. To provide insights into the potential mechanism of "NXTZ", this study attempts to deeply investigate the mechanism from two representative cardiovascular and cerebrovascular diseases, coronary heart disease (CHD) and cerebral apoplexy. First, various data resources were integrated to obtain different types of biomedical entities including drugs, targets, pathways and diseases. Then, three different approaches including text mining, biological network and enrichment analysis were utilized to recognize the potential common features between CHD and cerebral apoplexy, and the corresponding functions of drugs which could treat both diseases, thus unveiling the mechanism of NXTZ.

Objective To investigate the effect of individual nostalgia therapy on positive feelings and sadness of the spouses of postoperative patients with esophageal cancer. Method From June 2014 to June 2015, 60 hospitalized patients and their 60 spouses were set as control group. Routine health education and guidance were conducted once or two times a week for 7 weeks. Another 60 cases of hospitalized patients and their 60 spouses during July 2015 and June 2016 were set up as observation group. The patients were treated with the same nursing intervention as in the control group, and their spouses were subjected to individual nostalgia treatment once a week for 7 weeks. Before the intervention (postoperative day 2) and 7 weeks after the intervention, the positive aspects of caregiving (PAC) and the Margit-Meuser caregiver grief ineventary short form (MM-CGI-SF) were used to investigate their positive feelings and sadness. Result The score on spouse's positive feelings in the observation group after intervention was significantly higher than those of the control group and that of the observation before intervention (P < 0.01). Conclusion Individual nostalgia can effectively improve the feelings of the spouses of esophageal cancer patients and reduce their grief.

Traditional Chinese medicine (TCM) has definitely clinical effect in treating hyperlipidemia, but the action mechanism still need to be explored. Based on consulting Chinese Pharmacopoeia (2010), all the lipid-lowering Chinese patent medicines were analyzed by associated rules data mining method to explore high frequency herb pairs. The top three couplet medicines with high support degree were Puerariae Lobatae Radix-Crataegi Fructus, Salviae Miltiorrhizae Radix et Rhizoma-Crataegi Fructus, and Polygoni Multiflori Radix-Crataegi Fructus. The 20 main ingredients were selected from the herb pairs and docked with 3 key hyperlipidemia targets, namely 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase), peroxisome proliferator activated receptor-α (PPAR-α ) and niemann-pick C1 like 1 (NPC1L1) to further discuss the molecular mechanism of the high frequency herb pairs, by using the docking program, LibDock. To construct evaluation rules for the ingredients of herb pairs, the root-mean-square deviation (RMSD) value between computed and initial complexes was first calculated to validate the fitness of LibDock models. Then, the key residues were also confirmed by analyzing the interactions of those 3 proteins and corresponding marketed drugs. The docking results showed that hyperin, puerarin, salvianolic acid A and polydatin can interact with two targets, and the other five compounds may be potent for at least one of the three targets. In this study, the multi-target effect of high frequency herb pairs for lipid-lowering was discussed on the molecular level, which can help further researching new multi-target anti-hyperlipidemia drug.
